Incorrect alignment of the photos in the gallery b

Good Evening,
In the blue theme, I put 12 photos for display in the bottom tab of the detail page.
The first 4 pictures are in a div and lined up correctly.
ThE 8 more pictures are another div and alignment is not correct. There lag between the 4th and 5th pictures. The third line starts with an offset.

This is a copy of the code according to firefox inspector:

---

<!--
tab1
-->
<div id="gallery" class="tab-pane active">
<script src=" creatima.info/immologer/components/com_o...x/jquery.colorbox.js " type="text/javascript">
<link media="screen" type="text/css" href="http://......../components/com_osproperty/js/colorbox/colorbox.css" rel="stylesheet">
<script type="text/javascript"></script>
<div class="row-fluid">
<div class="span3"></div>
<div class="span3"></div>
<div class="span3"></div>
<div class="span3"></div>
</div>
<div class="row-fluid">
<div class="span3"></div>
<div class="span3"></div>
<div class="span3"></div>
<div class="span3"></div>
<div class="span3"></div>
<div class="span3"></div>
<div class="span3"></div>
<div class="span3"></div>
</div>
</div>

How can I restore the alignment for the third line?
